EJB Series Enclosures

High performance, high reliability enclosures for global applications

Featuring an optimized design and fast leadtimes for OEMs, ECP enclosures are available in 40 standard sizes with optional conduit and device drilling and tapping.

EJB junction boxes are used in threaded rigid conduit systems in hazardous areas:

  • As a junction or pull box
  • To provide enclosures for splices and branch circuit taps
  • For housing terminal blocks, relays and other electrical devices
  • Indoors or outdoors in damp, wet, dusty, corrosive, hazardous locations
  • Where exposure to frequent or heavy rain, water, spray, moisture and humidity is common, such as: offshore drilling facilities, cooling towers, coal preparation and handling facilities and sewage and waste water treatment
  • In areas which are hazardous due to the presence of hydrogen or gases and vapors of equivalent hazard such as found in process industries, missile bases and gas manufacturing plants
  • Style C boxes provided with aluminum plate cover as standard, allowing for field addition of cover device holes
  • Stainless steel cover bolts (Style C only)
  • Ground joint cover opening provides maximum opening for pulling wires or mounting equipment
  • Walls of bodies may be drilled and tapped for conduit entries as shown in listings
  • Stud bolts in diagonally opposite corners of body aid in aligning cover to body during installation (not furnished with hinged covers)
  • All Style C bodies are provided with captive, triple lead, quick release hex head stainless steel bolts with spring loaded action which provides clear indication that cover bolts are fully retracted from the body
  • External flange design – wide unobstructed cover opening provides a completely accessible interior for wiring and electrical equipment
  • Square corners of enclosure body provide maximum interior space and area for conduit openings
  • Internal grounding lug provides a means to ground enclosed equipment
  • Special neoprene cover gasket provides a watertight seal to meet NEMA 4 requirements, and provides superior protection for enclosed equipment against water/corrosion
  • IEC rated when ordered with ATEX suffix
  • Enclosures are machined for field installed mounting plates
  • Detachable mounting feet provide mounting flexibility; no need to replace enclosure if mounting feet are broken.
  • Optional stainless steel hinges provide convenient and easy access for inspection, maintenance and systems changes
  • Enclosures are machined to accept field installed hinges
